• 1

  United Kingdom publishes corporate tax figures in Pound Sterling, revised periodically — enter the rate currently in force for your case in United Kingdom rather than an older stored figure so the result matches the official calculation.

• 2

  Keep the corporate tax amount and rate for United Kingdom on one period and one basis — monthly Pound Sterling figures with an annual rate, or gross with net, give a number that is arithmetically right but misleading in practice.

• 3

  A corporate tax result for United Kingdom is only as current as the rate you typed in: when the figure matters, re-run it with a freshly confirmed Pound Sterling rate instead of one saved last month.

• Income tax is progressive: applying United Kingdom's top marginal band to a whole Pound Sterling salary overstates the bill, because only the slice above each threshold pays that band. Split the income into brackets instead of one flat multiplication.

• Gross and net are different numbers: a Pound Sterling salary quoted for United Kingdom is normally gross, and the Corporate Tax result only matches your payslip after United Kingdom deductions and contributions are subtracted. Confirm which side each input represents.
